HEATER.

Be it known that I, FRANK R. Pn'r'rrrna citizen of the United States,and a resident of Portland, county of Multnomah, State of Oregon, haveinvented certain new and useful Improvements in Heaters, of which thefollowing is a specification; I

My invention relates to heaters in general, and particularly to heatersadapted for use upon hydro-carbon motors for the purpose of heating thefuel intake manifold, the object being to aid in the starting of themotor by completely vaporizing the fuel gas.

I accomplish this object by means .of the construction illustrated inthe accompanying drawing, which is a part of this applica;

' tion for Letters Patent, like characters of reference indicating likeparts throughout the several views of the drawing, and in which:

Figure 1 is a side elevation of my device applied to the motormanifolds.

Fig. 2 is a sectional elevation upon line 22 of Fig. 1.

Fig. 3 is a section upon line 3-3 of Fig. 1.

Fig. 4 is a perspective view of one of the manifold casing members.

Fig. 5 is a perspective view of the heater. 1

In general my device consists of a split casing adapted to surround theintake and exhaust manifolds of the motor, and a heater adapted toattach to said casing and provide heat therein.

Said casings surround the intake manifold 6 and the exhaust manifold '7,each portion of. the casing consisting of a body 8 adapted to conform tothe shape of the manifolds and to completely surround the Y same whenthe two portions of the casing are in place, alined flanges 9 adapted toclosely surround the exhaust manifold when the casing is in .place, anda depending flange 10 adapted to surround the depending portion of theintake manifold when the casing is in place.

When the two portions 8 of the casing are in place they are secured byencircling bands or clamping rings 11 upon each of *the flanges 9 and10, as shown in Fig. 1.

The heater 12 is an inclosed box like structure provided at its upperend with an open circular flange 13, which flange is adapted to slipover the assembled flanges 10 of the casing and receive its respectiveclamping ring 11 upon the outside thereof.

A vertically disposed slot His provided Specification of Letters Patent.Patntd Aug. 31, 1920.

in said flange 1 3 to receive the lower endof the intake manifold andallow the same to protrude'th erefrom, as shown. in Fig. 1. sald slot14. also renders the flange 13 somewhat yielding so it may be readily00111 pressed within its clamping ring 11 and thereby caused to securelyclamp the flanges- 10 of the two portions of the casing 8gtogether.

In the lower portion of the heater 12 is formed a fuel receptacle 15,shown in the drawings as adapted for liquid fuel, such as coal oil orthe like, having afilling opening closed by a cap 16, and a lamp burner17- disposed lmmediately beneath the open flange 13, and adapted toimpinge its flame openings 21 are provided in the heater for I theadmittance of air to the lamp.

My invention may be made of anysize and constructed'of any materialdeemed convenient and suitable for a device of this character, and whileI have illustrated and described a form of construction and .ar-;

rangement of parts found desirable in materializing my invention, I wishtoinclude in thisapplication for Letters Patent all mechanicalequivalents and substitutes that may fairly be considered to come withinthe scope and purview of my invention as defined in the appended claim.

Having disclosed others may be enabled to construct and to my inventionso that use the same, what I claim as new and desire to secure byLetters Patent is:

1. In a heater for hydro-carbon motors. a casing adapted to inclose thegas intake manifold of said motor; a downwardly pro- 7 jecting openflange upon said. casing; a

heater an upwardly projecting flange upon said heater; and means tosecure said flanges togethen.

2. In a heater a split casing adapted to inclose the gas intake andexhaust manifolds of the motor;

horizontally disposed alined flanges upon said casing adapted to besecured to the ex-. haust manifold; a downwardly pro ect1ng' forhydro-carbon motors,

end of the gas intake manifold; and means to secure said downwardlyprojecting and said upwardly proj e'cti'n'g flanges together;

3. In a heater for hydrmcar-bonn10tors;-a two piece casing adapted to'inclose the manifolds of the motor, each' member ofsaid casingconsisting of a body, a pair of oppositely disposed horizontallyalinedhalf flanges; and a downwardly projectinghalf flange the correspondinghalf flanges 00 operating: to form a whole flange adaptedto encompasscertain of said manifolds,

and. means to clamp said casing in place upon said manlfolds; incombination wlth a heater consisting of a flange adapted to receivetherein each of said downwardly proin the presence of two subscribingwitnesses,.
